Apparatus for carrying out polymerization reactions or for evaporating solutions comprises a horizontally disposed cyclindrical vessel 8 containing a rotatable agitator 9 in the form of a cylindrical cage. The agitator comprises two spoked end wheels 20 and 21 supported on rotatable shafts 18 and 19 and joined by horizontal peripheral bars 23, rods 22 connecting the bars and arranged in a generally helical formation so forming the cylindrical surface of the cage, and wires 30 and 31 lying within the cage in planes perpendicular to the horizontal axis of the vessel. A heating jacket 25 surrounds the vessel. Liquid enters through inlet 12, and is heated and flows through the vessel to the outlet 13, by the action of the rotating bars 22 which carry the liquid up and together with the wires cause the formation of the liquid film in the vessel. The vapour formed flows out through vent 15. A blade 24 at the outlet end wipes the end wall but allows the vapours to flow to the outlet 15. The apparatus may be used for the production of polyethylene terephthalate by heating bis-2-hydroxyethyl terephthalate with evolution of ethylene glycol until the desired viscosity is achieved.

Title: Improvements in or relating to radio receivers

Abstract: 426,893. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Carlson, W. La V.; 726, Clinton Avenue, Haddenfield, and Kirkwood, L. R. ; 6220, Wayne Avenue, Merchantville, both in New Jersey, U.S.A.) Dec. 22, 1933, No. 36134. Convention date, Dec. 22, 1932. [Class 40 (v)] A noise-suppressor circuit comprises means for reducing the amplification of an amplifier preceding the detector when the received signal strength is below a predetermined level. The invention is shown applied to superheterodyne receiver comprising a radio frequency amplifier 1, local oscillator 3, first detector 2, intermediate frequency amplifier 4 and second detector 5. The noise suppression and automatic volume control potentials are developed by a double diode triode valve 18, the diode anodes 19, 20 of which are fed from an independent intermediate frequency amplifier 16 which receives its input through condenser 17, from the output of the first detector 2. The load circuit of the diode portion 20, 19<1> comprises resistances 21, R2, R3 from tappings on which A.V.C. potentials are led to the valves 1, 2 and 4. The volume control action is delayed by the positive voltage applied to the cathode 191 from the cathode resistance of valve 4. The latter is also included in the plate circuit of the triode portion of valve 18 and is adapted to block the grid of valve 4 when current flows in said plate circuit. This occurs when the diode 19, 19<1> is receiving signals of below a predetermined value and its load resistance R12 connected to the triode grid is carrying a correspondingly small current. The sensitivity and noise suppression threshold valve are controlled by a manually variable cathode resistance R18 which carries current, through a resistance R14, from the H.T. supply and biasses valves 1 and 2 to a variable extent. The knob 34 controlling resistance R18 also controls a switch 28 adapted to break the plate circuit of the triode portion of valve 18 to disable the noise suppressor. The requirements as regards selectivity of the various intermediate frequency circuits are discussed. In a modification, Fig. 2, (not shown), the A.V.C. amplifier and rectifier are comprised in a single pentode valve and a further auxiliary amplifier feeds a single diode triode noise suppressor valve. A tuning lamp is coupled to the anode circuit of a valve supplied from an A.C. source and whose grid is controlled by the noise suppressor valve so that the lamp is extinguished when no signals are being received. Specifications 417,284 and 424,779 are referred to.

In a road vehicle power-assisted steering mechanism wherein a lost motion is provided between the steering output of a manually operable steering component and the input to the steering transmission by means of which the regulating part of a valve for controlling the supply of fluid to the power means is operated, the two parts of the control valve are biased to a neutral position by a spring system which is anchored to one part of the valve (or to a part moving with it) and which is in engagement with the other part of the valve (or a part moving with it). The steering shaft 13, Fig. 1, manually rotatable by a steering wheel, is connected by a lost motion device to a threaded member 10 which is engaged by a unit 8 cooperating with the thread by balls 9, the unit 8 being attached to a piston 5 operating within a cylinder 6 and provided with a rack engaged by a pinion 2 mounted on a shaft 3 connected by a drop arm to the steering transmission. The shaft 11 is keyed to the rib 16 of a member 12, Fig. 5, which is also provided with a rib 15 engaging with tolerance a groove in the steering shaft 13. A sleeve 19 mounted on the shaft 13 is keyed to the member 12 and a blade spring 18 is secured at its ends to the sleeve 19 and is closely received at its central part in a diametral groove in the shaft 13.
